Video Review of the Transformers Hunt for the Decepticons; Scout Class Brimstone There was a time when BRIMSTONE was king of the roads on CYBERTRON. He was meaner, faster and tougher than anything else on wheels, and he made sure everyone knew it.

BRIMSTONE may be older now, but he’s also meaner, and there’s no way he’s going down without taking HUBCAP with him.
